Efficiency Policies window

Contributors netapp-ivanad

You can use the Efficiency Policies window to create, display, and manage information about efficiency policies.

Command buttons

  • Add

    Opens the Add Efficiency Policy dialog box, which enables you to run a deduplication operation on a volume for a specified duration (schedule-based) or when the change in volume data reaches a specified threshold value (threshold-based).

  • Edit

    Opens the Edit Efficiency Policy dialog box, which enables you to modify the schedule, threshold value, QoS type, and maximum run time for a deduplication operation.

  • Delete

    Opens the Delete Efficiency Policy dialog box, which enables you to delete the selected efficiency policy.

  • Status

    Open a drop-down menu, which provides options to enable or disable the selected efficiency policy.

  • Refresh

    Updates the information in the window.

Efficiency policies list

  • Policy

    Specifies the name of an efficiency policy.

  • Status

    Specifies the status of an efficiency policy. The status can be one of the following:

    • Enabled

      Specifies that the efficiency policy can be assigned to a deduplication operation.

    • Disabled

      Specifies that the efficiency policy is disabled. You can enable the policy by using the status drop-down menu and assign it later to a deduplication operation.

  • Run By

    Specifies whether the storage efficiency policy is run based on a schedule or based on a threshold value (change log threshold).

  • QoS Policy

    Specifies the QoS type for the storage efficiency policy. The QoS type can be one of the following:

    • Background

      Specifies that the QoS policy is running in the background, which reduces potential performance impact on the client operations.

    • Best-effort

      Specifies that the QoS policy is running on a best-effort basis, which enables you to maximize the utilization of system resources.

  • Maximum Runtime

    Specifies the maximum run-time duration of an efficiency policy. If this value is not specified, the efficiency policy is run till the operation is complete.

Details area

The area below the efficiency policy list displays additional information about the selected efficiency policy, including the schedule name and the schedule details for a schedule-based policy, and the threshold value for a threshold-based policy.
